Rounding numbers?

[Gavin Roberts]

Hi all, I was wondering if there is anyway that you could use Math.Round or some other method/class to round numbers off. Basically if I have the number 19 or 256 etc I would like to round it off to the nearest ten, ie 19 rounded to 20 256 rounded to 260 I've tried using Math.Round but that only works for decimals. Any idea's? TIA Gav

The following should work:

double x = 256;
x = Math.Round(x / 10.0) * 10.0;

i dont know if there already is a function. if not try this: function roundup(int myval) { while (myval % 10 != 0) myval++; return myval; } usage: roundup(15); output: 20 if you want it to use the "real" rules, you will have to do it like this: function round(int myval) { int runs = 0; while ((myval + runs) % 10 != 0) { runs++; } if (runs < 5) return (myval - 10); return myval; } EDIT: the post before this one shows another solution which is much simpler and also looks better (since it's using inbuilt technology it probable will be faster too :))
